Abstract
A hot melt adhesive composition comprising at least 40% by weight of an unmodified semi-crystalline propylene polymer comprising at least 50% by weight propylene and at least 15% by weight of a wax.
Description
Background
The present invention relates to the preparation of hot melt adhesive compositions comprising a semi-crystalline propylene polymer and a wax.
Hot melt adhesive compositions typically include a polymer and a tackifier and in some cases a wax or oil. Hot melt adhesives for packaging should exhibit good bond formation, heat resistance and thermal stability and fast set times to be commercially useful. It is difficult to formulate propylene polymer based hot melt adhesive compositions that exhibit the performance properties that must be met for the packaging adhesive to be commercially useful. Tackifiers can, for example, cause discoloration and charring of the hot melt adhesive. Waxes have a detrimental effect on the bond formation of polypropylene hot melt adhesive compositions. This is particularly true for waxes with high crystallinity. Oils are known to reduce the setting speed of hot melt adhesive compositions. Oil can also bleed out of the hot melt adhesive composition and cause undesirable staining of the substrate to which it is bonded.
It is desirable to obtain a hot melt adhesive composition based on propylene polymers that exhibits good adhesion at low and high temperatures, thermal stability, fast set time and very low to no oil stain and oil migration.

The hot melt adhesive composition can be applied to or incorporated into a variety of articles including, for example, fibers, substrates made from fibers (e.g., virgin fibers), recycled fibers, synthetic polymer fibers (e.g., nylon, rayon, polyester, acrylic, polypropylene, polyethylene, polyvinyl chloride, polyurethane), cellulosic fibers (e.g., natural cellulosic fibers such as wood pulp), natural fibers (e.g., cotton, silk, and wool), and glass fibers, and combinations thereof), release liners, porous substrates, cellulosic substrates, sheet materials (e.g., paper and fiber sheets), paper products, woven and nonwoven webs (e.g., webs made from fibers (e.g., yarns, threads, filaments, microfibers, blown fibers (blon fibers) and spun fibers (spun fibers)), perforated films, and combinations thereof), tape backings (tape backings), and combinations thereof.
The hot melt adhesive composition can be used to bond a variety of substrates including, for example, chipboard, coated chipboard, paperboard, fiberboard, virgin and recycled kraft, high and low density kraft, chipboard, treated and coated kraft and chipboard, and corrugated forms thereof, clay coated cardboard stock (clay coated chipboard stock), composites, leather, fibers and substrates made from fibers (e.g., virgin fibers, recycled fibers, synthetic polymer fibers, cellulosic fibers, and combinations thereof), release liners, porous substrates (e.g., woven webs, nonwoven webs, and perforated films), cellulosic substrates, sheets (e.g., paper and fiber sheets), paper products, tape backings, and combinations thereof.
The hot melt adhesive composition can be used to bond a first substrate to a second substrate in a variety of uses and configurations, including, for example, packaging, bags, boxes, cartons, cases, trays, multi-layer bags, articles including accessories (e.g., a straw attached to a beverage box), ream wrap, cigarettes (e.g., plug wrap), filters (e.g., pleated filters and filter frames), bookbindings, paper products including, for example, paper towels (e.g., multipurpose towels), toilet tissue, facial tissue, wipes, tissue, towels (e.g., paper towels), and combinations thereof.

In on-demand hot melt application systems (which are also referred to as "tank free" and "tank less" systems), the hot melt composition is fed in a solid state (e.g., pellets) into a relatively small heating vessel (as opposed to conventional hot melt application systems that include a tank) where the hot melt composition is melted and, typically shortly thereafter, the molten liquid is applied to a substrate. In on-demand systems, relatively large amounts of hot melt compositions generally do not remain molten for long periods of time. In many existing on-demand systems, the volume of the molten hot melt composition is no greater than about 1 liter or even no greater than about 500 milliliters, and the hot melt composition remains molten for a relatively short period of time, including, for example, less than 2 hours, less than 1 hour, or even less than 30 minutes.

(Minneapolis, Minnesota) and the Free Hot Melt Dispensing System from Nordson Corporation (Westlake, Ohio). On-demand hot melt adhesive application systems are described in U.S. patent publication nos. 2013-0105039, 2013-0112709, 2013-0112279 and 2014-0042182 and U.S. patent No.8,201,717 and incorporated herein.
The invention will now be described by way of the following examples. All parts, ratios, percentages, and amounts specified in the examples are by weight unless otherwise specified.
Examples
Test procedure
The test procedures used in the examples include the following. All ratios and percentages are by weight unless otherwise indicated. Unless otherwise specified, these procedures are carried out at room temperature (i.e., ambient temperature of about 20 ℃ to about 25 ℃) and ambient humidity (i.e., 30% to 70%).
Method for determining molecular weight
Molecular weights (Mn, Mw and Mz) were determined using Polymer Labs PL-GPC 220 high temperature size exclusion chromatography (HT-SEC) run at 160 ℃ with 1,2, 4-Trichlorobenzene (TCB) as the mobile phase. The system contained three PL gel mixed B columns in series and was equipped with a Refractive Index (RI) detector. SEC was run at an injection volume of 100 microliters at a flow rate of 1.0 ml/min. All HT-SEC samples were prepared at a concentration of 4.0 mg/ml. Molecular weights were calculated from the Mark-Houwink relationship using known polystyrene standards. For polystyrene, the Mark-Houwink parameters are K0.000121 and α 0.707; for polypropylene, the Mark-Houwink parameters are K0.000190 and α 0.725. Results are reported in grams per mole (g/mole).
Viscosity test method
The viscosity was measured according to ASTM D-3236 (10/31 1988) entitled "Standard Test Method for applied viscosity of Hot Melt Adhesives and Coating Materials" using a Brookfield viscometer, a Brookfield Thermosel heated sample cell, and a 27 spindle. Results are reported in centipoise (cP).
Solidification time test method
A bead of the adhesive composition, measured as 5.08cm x0.24cm, was applied to a first substrate of RockTenn 56SK-23ME-56SK high performance 44 pound ECT 87% virgin liner (virgin liner board) using a MEC ASM-15N hot melt adhesion simulator at 177 ℃.2 seconds after the adhesive bead was applied to the first substrate, the adhesive bead was contacted with a second substrate of RockTenn 56SK-23ME-56SK high performance 44 pound ECT 87% virgin liner, which was then pressed against the first substrate at a pressure of 0.21MPa for a period of time (referred to herein as the compression time). The bond simulator timer is started when the substrate is compressed. After a pre-programmed compression time, the instrument separates the two substrates by pulling the second substrate in the Z-direction and holding the first substrate in a fixed position, and measures the force required to separate the substrates and the amount of fiber tear present on the adhesive composition. Samples were run in triplicate at each compression time. Initially, the compression time was 0.5 seconds. If the three samples fail to exhibit greater than 50% fiber tear for each sample, the compression time is increased by 0.1 seconds and the test method is repeated until greater than 50% fiber tear is noted for all three samples. Set time was recorded as the compression time for these three samples to achieve greater than 50% fiber tear upon separation. The clotting time was recorded in seconds.
Thermal stress resistance test method
Thermal Stress Resistance was measured according to the standard IOPP T-3006 entitled "coated Test Method for Determining the Heat Stress Resistance of Hot Melt Adhesives" using an onset temperature of 46℃ (115F), a load of 200 g per sample and 5 adhesive samples per adhesive. After each 24 hours, the number of samples that no longer supported the weight was recorded and the temperature was increased by 2.8 ℃ (5.0 ° F). The pass temperature (pass temperature) of each adhesive, defined as the maximum temperature at which 80% of the sample remains bonded, is the resistance to thermal stress and is reported in degrees Celsius (C.).
Fiber tear test method
The percent fiber tear is the percentage of fiber covering the area of the adhesive after the two substrates previously bonded together by the adhesive are forcibly separated. The percent fiber tear exhibited by the adhesive composition was determined as follows. A bead of adhesive composition measuring 15.24cm (6 inches) x0.24cm (3/32 inches) was applied to a first substrate of ROCKTENN 56SK-23ME-56SK 44 pound ECT 87% virgin liner using a ROCKTENN adhesion simulator at a specified application temperature. 2 seconds after the adhesive bead was applied to the first substrate, the adhesive bead was contacted with a second substrate of RockTenn 56SK-23ME-56SK 44 pound ECT 87% virgin liner, which was pressed against the adhesive and first substrate at a pressure of 0.21MPa (30 pounds per square inch (psi)) for 2 seconds. The resulting construct was then conditioned at room temperature for at least 4 hours, and then at the specified test temperature for at least 12 hours. The constructed substrates are then separated from each other by pulling the two substrates apart from each other by hand at the conditioning temperature (e.g., immediately after removing the sample from the conditioning chamber). The surface of the binder composition was observed and the percent surface area of the binder composition covered by the fibers was determined and recorded. A minimum of five samples were prepared and tested for each hot melt adhesive composition. Results are reported in% fiber tear.
Thermal stability test method
A 200 gram sample of the hot melt adhesive composition was placed in a glass beaker (no lid) and conditioned in a temperature controlled forced air oven at 177 ℃ for 200 hours. The molten sample was removed from the oven. The molten sample was observed for the presence of gels, surface skinning and charring. The observations were recorded.
The samples were then tested according to the viscosity test method and the measured viscosity was expressed in centipoise.
Thermal stability is determined by the change in viscosity and the presence or absence of charring or skinning.
Melting point test method
The melting Point is determined according to ASTM D-3461 entitled "Standard Test Method for Soft lifting Point of Ashaltand Pitch (Method Cup and Ball Method)" with a heating rate of 2 ℃ per minute.
Gardner color
The samples (in the melt state) were tested to determine the Gardner color by comparing the sample colors against a Gardner color standard as set forth in ASTM D-1544. The comparison was performed using a Gardner Delta comparator equipped with an illuminator available from Pacific Scientific (Bethesda, Maryland). Results are reported as values relative to the Gardner color standard.
